The GraphQL field `id` of `Node`s should also encode the locale

[simonwacker]

For the reasons see https://github.com/building-envelope-data/api/blob/f75edaac57e325092effceca10177ae11d2c3164/apis/database.graphql#L1-L10 and https://github.com/building-envelope-data/api/blob/f75edaac57e325092effceca10177ae11d2c3164/apis/database.graphql#L417-L440 Currently, it encodes only the UUID (together with the table name to be unique in the database), see

database/backend/src/GraphQl/Entities/EntityType.cs

Lines 17 to 24 in d45f78d

	descriptor
	.ImplementsNode()
	.IdField(t => t.Id)
	.ResolveNode((context, id) =>
	context
	.DataLoader<TEntityByIdDataLoader>()
	.LoadAsync(id, context.RequestAborted)! // Notice the null-forgiving operator `!`. It's bad that we need to use it here.
	);

, and thus violates field stability. The same is true for the metabase project.
